The main failure modes for junction boxes include detachment (from the module backsheet), poorly sealed or closed boxes, corrosion, and arcing due to bad or degraded wiring. Degradation and failure of junction box components can lead to major performance losses and safety hazards because of the high current levels passing through [25, 26, 108].
Partial shading and fading in the heat are the most critical failure modes due to external events. The partial shading effect is primarily due to new construction near the panels and grass growing above the height of the solar panels. Proper care can significantly minimize the probability of partial shading and new shading elements.
Failure of the solar cell mainly occurs due to the very thin profile of the silicon wafer. These thin wafers are very brittle and are prone to cracking easily during manufacturing or transportation. Generally, microcracks of the cell cannot be detected by the naked eye. Consequently, they may spread and distribute to other cells in the module .
The failure of the components affects the reliability of solar PV systems. The published research on the FMEA of PV systems focuses on limited PV module faults, line-line contact faults, string faults, inverter faults, etc. The literature shows that the reliability analysis method is used to evaluate different faults in PV systems.
The greatest challenge that the today's researchers find in analysing the solar photovoltaic systems is the absence of sufficient quantitative failure and repair data. The researchers have highlighted this problem their work and presented a study that largely relies on the qualitative approach and approach.
External factors such as declines in the price of natural gas, the energy source solar was intended to replace in the city, have also contributed to the unprofitability of the plant, with consumers more likely to purchase power from natural gas sources, rather than the solar plant.
The risk priority analysis is considered one of the promising approaches for identifying the severity of failure modes. The study reports shows that the inverter and ground system has a failure mode with high RPN. Table 1 summarizes various faults related to solar PV systems as reported in the literature studied. Table 1.

Solar power systems are also expected to play a significant role during a disaster, because they can provide backup electricity in the event of power failure. When the Great Hanshin-Awaji Earthquake occurred in 1995, disruption of lifeline services, such as electricity, water and gas, made rescue operations more difficult, thus resulting in more serious damage. Learning from …

in the blackout of an entire power system, then generators with blackstart capability are required to restart the system. Wind (and solar) generation have not traditionally been associated with such a role. What open issues exist for wind (and solar) power contributing to system stability?
